The options under AI Instructions — what each one is for.

One tick that sets everything marketplaces expect: 1K resolution, Portrait 3:4, JPEG. Use it for Meesho, Amazon and Flipkart listings.
1K is sharp enough for WhatsApp and marketplace listings. 2K–4K for zoomable website images, 8K for print. Higher resolutions can cost more credits — the Generate button always shows the cost before you tap.
A free-text box for anything specific: “model should smile”, “evening light”, “show the border clearly”. Keep it to one or two short lines — it overrides other settings, so only write what you really want enforced.
